Former big kid and current soap star, Sean Kanan, is among those joining the discussion.

A teenager wears a fake baby bump to school as a social experiment. HLN's Dr. Drew takes a closer look.

An Italian cruise ship crashed off the Italy Tuscan coast Friday night, sending 4,200 people into a state of panic. On Monday night, Dr. Drew talked to the Ananias family who survived the tragedy. They explain how they helped people, including a baby, off the ship almost until the very end.

“Many times as the ship was tilting - we were with a family on the life boat and they had a little 3-year-old," Georgia Ananias said. "We stayed as a team. We pulled each other up ... All of the sudden ... a father turned to me and said, 'take my baby, take my baby' … I held the baby and then as the gravity was pushing - it was pulling me - and we`re at the top of a stairwell and I knew that eventually the baby would just fall out and fall down the stairwell … I said 'you have to take your baby back' - and I don`t know where they are now."

Georgia's daughter, Valerie, added, "I`m absolutely distraught ... my thing was to get the children off the boat."
